Using Int to get a value from a string?

**Sidonius** · October 10th, 2014, 12:54 AM

This post retains to the default code given when you decompile Minecraft and... Obfuscate it? I'm not sure the correct terms yet, so please excuse me.
Anyways, variable names I have gotten from the code I've gotten from Minecraft using MinecraftCoderPack & Eclipse. Please don't hound me about the variable names. I am trying my best based on what I know now. I am still learning Java scripting.

I believe I posted something similar, or about this a while ago, but I was not able to understand the response fully to the point I could implement it to my needs.

So... I have a string that I am wanting to get a number from.

Example:
public static final String[] exampleLetters = new String[] {"a", "b", "c", "d", "e", "f", "g"};

And, using a public Int (with no variables in the title), I am looking to take numbers for each string letter, to be able to output the value to other code.
Example:
public int letterConversion()

a = 0, b = 1, and so on to g = 6
I hope you get the idea.

How would I be able to get the numerical values of each letters using a public Int without any variables in the title?

I am not looking for someone to code my Minecraft mod, I am just looking for a point of reference to do what I am trying to for this specific sector I am working on at the moment.

---

Actual Code I have right now. Again, please ignore variable names, it's what I got use to while learning.

/** The list of the types of step blocks. */
    public static final String[] slabType = new String[] {"stone", "sand", "cobble", "brick", "smoothStoneBrick", "netherBrick", "quartz"};
 
 
    }
 
    /**This checks slabType for the material and registers a number to each type for other codes to use.*/
    public int textureType()
    {
    	int var1 = -1;
    	{
    		for ( int var2 = 0 ; var2 < slabType.length ; var2++ )
    		if (var2 == 0) return var1 = 0;
    		else if (var2 == 1) return var1 = 1;
    		else if (var2 == 2) return var1 = 2;
    		else if (var2 == 3) return var1 = 3;
    		else if (var2 == 4) return var1 = 4;
    		else if (var2 == 5) return var1 = 5;
    		else if (var2 == 6) return var1 = 6;
    	}
        return var1;
    }

For what I have now, in the Int...

for ( int var2 = 0 ; var2 < slabType.length ; var2++ )

Is controlling the output. No mater what the 0 is the output, and I am not sure exactly why due to my still learning.

Lets start with a basic point: your for loop.

int var1 = -1;
{
    for ( int var2 = 0 ; var2 < slabType.length ; var2++ )
        if (var2 == 0) return var1 = 0;
        .....
}

Firstly, consider where your brackets are placed, where have you placed them around the outside of the for loop?

Secondly, let us read the statement above: Instantiate variable 2 to having value 0, while its value is less than the length of slabType, increment it by one, performing the statements enclosed each time.
So for variable2=0, if variable2 is equal to zero, we return 0, and end execution, do you see the problem here? Consider what you are telling the program when you say 'return xxxx'.

As a quick question so I might be able to help more after, are you trying to have a set of string values, which each have an integer value attached to them?
So for instance, rock = 1, paper = 2 and scissors = 3?
Then another method can say value 1, and you know you have a rock?

I am not sure if this site is considered decent for learning the basics, but it's what I'm using at the moment to learn just Java for now. Learn | Codecademy
So I don't yet know a lot of the basic stuff I should, but I can usually figure out how to implement stuff when I see it used in other code.

I am not sure how I'd increment slabType one by one, I don't think I've gotten that far into my learning yet. Could you show me an example?

Anyways, this is a basic diagram of what I am trying to do with the code:

The blue being what I already have working based on test.

What do you mean increment slabType? that is of String[].. which you cannot increment.

Based on @AGunner 's reply to the post. I'm not sure if that's the right term, I think It's supposed to be incrementing the values in the int? I am uncertain.
